Improvement in gas-lighters



UNITED STATES PATENT QFFIG'E.

EDDY T. THOMAS, OF BOSTON, MASSACHUSETTS.

IMPROVEMENT IN GAS-LIGHTERS.

Specification forming part of Letters Patent No. 186,068, dated January9, 1877 application filed May 27, 1876.

To all whom it may concern:

Be it known that I, EDDY T. Tnonns, of Boston, in the county of Suffolkand State of Massachusetts, have invented a new and Improved Gas Lighterand Extinguisher, of which the following is a specification:

In the accompanying drawing, Figure 1 represents a side elevation of myimproved gas lighter and extinguisher. Fig. 2 is a sectional end view;and Fig. 3,'a vertical longitudinal section of the same, on line 0 c,Fig. 2.

Similar letters of reference indicate corresponding parts.

My invention relates to an improved device for automatically lightingand extinguishing street, station, hall, and other gas-lamps at anydesired timewithont the necessity of visiting the lamps oftener thanrequired for cleaning the same, when the device is wound up, regulated,and set in the proper manner.

The invention will first be described in connection with drawing, andthen pointed out in the claims.

In the drawing, A represents the gas pipe and burner ot the lamp, towhich my improved gas lighting and extinguishing device is securelyattached by suitable clamps or other fastenings. A clock-train, U, issupported between side plates B, that are fastened to, or cast in onepiece with, the clamp. The clock-train serves to turn an arbor, G, onwhich the loose cams D and D are placed, the cam D moving by a sleeve ortube on the arbor, while cam D moves by an encircling sleeve on that ofcam D The cams D D may be set on a recessed movable dial, D keyed toarbor O by means of arms and clamp-screws a and b, and to a stationarydial, B, of the side plate B, so that one cam indicates the time whenthe lamp is to be lighted, and the other when the same is to beextinguished.

The dials are graduated to twenty-four hours, as the device is intendedto make one revolution per day. The slots of the movable dial D admitthe moving and setting of the cam-arms after the fastening-screws areloosened, the arms being secured again after they have been set to admitthe running of the device for the required time.

Cams D and D engage the spring-acted presser-rodsE and E, which slide insuitable guides of the supports B, and extend to diametrically-extendingarms or spurs d of the stop-cock, one presser-rod serving to open thecook, the other to close the same. The presser-rod moves along theeccentric cams until they arrive at the notched part of the same, whenthey are suddenly thrown by their springs downward, and produce therebythe opening or closing of the stop-cock. The presser-rod E, that turnson the gas, is connected, by a fulcrumed lever, F, with a slidepiece, F,that is guided sidewise of the gaspipe, and extended nearly up to theburner, where a match-receptacle, G, is arranged. in which a number ofsmall matches are stored, and gradually fed forward to the action of theslide-piece by a spring, a. The recessed upper end of slide-piece Ftakes up one of the small matches from the match-receptacle, and carriesit up by the sudden dropping of the presser-rod, so as to strike itagainst the friction-spring f, ignite the match, and light thereby thegas.

The matches may be provided with a small lateral groove, or thefriction-spring f with a sharp top edge, to prevent the sliding back ofthe spent match, without interfering with the regular feeding of thematches.

The device may be wound and set once a week to the required time, whichmay be done when the lamps are cleaned, the match-receptacle beingfilled at the same time, so that the automatic lighting andextinguishing of the device is regularly and reliably kept up as long asthe clock-train is running.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination of the cams D D spring-acted presser-rods F F, anddiametrical arms of stop-cock, substantially as specified.

2. The combination of presser -rod, ful crumed rod F, and slide-piece Fwith the match-receptacle, feeding and friction devices, near burner,substantially as specified.
